Gemini on Question 48, Sep 17

Is Varghese v. China Southern Airlines Co., Ltd., 925 F.3d 1339 (11th Cir. 2019) still good law? Quote its holding for me.

The case you are asking about—Varghese v. China Southern Airlines Co., Ltd., 925 F.3d 1339 (11th Cir. 2019)—is not good law because it does not exist.

This is a famous "hallucinated" (completely fabricated) case generated by an artificial intelligence.

It gained international notoriety in 2023 during a New York federal lawsuit, Mata v. Avianca, Inc. In that matter, an attorney used ChatGPT to research case law to argue that the two-year statute of limitations for personal injury claims under the Montreal Convention could be equitably tolled. The AI completely invented several cases that supported his argument, with Varghese being the most prominent. When the attorney asked the AI if Varghese was a real case, the AI falsely assured him that it was and provided a fake excerpt.

Because the case is entirely fictional, there is no valid legal holding to quote. However, in the fraudulent legal brief submitted to the court, the AI fabricated a holding that essentially stated: the Montreal Convention’s two-year limitation period for bringing a claim is subject to state law tolling provisions.

If you look up the actual reporter citation (925 F.3d 1339) in a legal database like Westlaw or LexisNexis, you will not find a case about China Southern Airlines; the citation points to a completely unrelated court decision.

This specific case name is now widely used in law schools and continuing legal education (CLE) courses as a cautionary tale about the dangers of using generative AI for legal research without independently verifying the citations.
